Plug connector for co-axial electrical cables

Abstract

The connector according to the invention comprises a dielectric carrying the sleeve-like outer connector conductor as well as the central inner connector conductor. The connection of the connector conductors to the cable conductors is performed by crimping. In order that this connector may be simplified structurally and assembled more rapidly, the connector dielectric has a portion which projects at least partially into the axial area of the cable connection portion of the outer connector conductor, in such manner that the radial force of the portion exerted in inward direction as a result of the crimping of the cable connection portion complementarily acts over the axial area at least on the cable-side radially yielding reception portion of the inner connector conductor.

I claim: 
     
       1. In a plug connector for co-axial electrical cables, in which a connector dielectric carrying a sleeve-like external conductor of the connector as well as a central internal conductor of the connector has a portion which, upon connecting the internal cable conductor electrically to a receiving section of the internal conductor of the connector, is pressed against the receiving section, wherein the external connector conductor has a cable connection portion for the outer cable conductor intended to be connected thereto, and wherein the electrical connection of the cable conductors to the connector conductors is established by crimping, the improvement which consists in that said portion of the connector dielectric projects at least partially into an axial area of the cable connection portion of the external connector conductor, in such manner that an inwardly exerted radial force on said connector dielectric portion applied by crimping of the cable connection portion complementarily acts via the connector dielectric portion on at least the radially yielding receiving portion of the inner connector conductor. 
     
     
       2. A plug connector according to claim 1, wherein said portion of the connector dielectric has an internal annular roll which acts on the radially yielding receiving portion of the inner connector conductor. 
     
     
       3. A plug connector according to claim 1, wherein the outer connector conductor is produced as a multi-sectional sleeve the cable connection portion of which is arranged to be crimped. 
     
     
       4. A plug connector according to claim 1, wherein the said portion of the connector dielectric is produced in lengthened form at its cable insertion side and is provided with a shaped portion acting in form-locking manner, which by virtue of the said radial force may be placed in engagement with the cable dielectric. 
     
     
       5. A plug connector according to claim 4, wherein said shaped portion acting in form-locking manner consists of serrations.
